To avoid nesting, this might be better written as:

if (index)

Do you really need to check for em->ring here?  You already return if
the value of the indicator is already the same.  Also, it sounds like
you should just start a timer and always call ring_cb when callsetup ==
callsetup_incoming.  The CCWA/RING determination should be done in that
function.

I agree with you that check of em->ring when callsetup becomes INCOMING 
is useless.
I thought that the second one, when callsetup is no more INCOMING, 
should be kept to stop the timer as soon as callsetup change states.

I don't like this.  I'd rather we add

struct ofono_call *__ofono_voicecall_find_call_with_status(struct
ofono_voicecall *vc, int status) to ofono.h/voiecall.c

You can probably get rid of incoming_str and incoming if you use
__ofono_voicecall_find_call_with_type...

Keep this simple, I really wouldn't try to optimize a strcpy operation.

Can you move this into its own function, e.g.
unregister_emulator_handlers or something like that.  There will be lots
of these and I don't want to clutter up voicecall_unregister too much.

Otherwise looks good, but does not apply.  Could you please rebase &
resubmit?

I'd rather not do this, you're not really avoiding a race condition with
MPTY hangups or HangupAll here.  I'd rather we re-use release_queue but
add additional sanity checking.  Perhaps adding a callback parameter to
voicecalls_release_next might make this easy.  In general we need to
think some more about how to avoid clashes between the D-Bus API and the
emulator.

Why are you checking this here?  Shouldn't you check this before
potentially sending a hangup_active?

For simple structures (e.g. under 1k or so) it is fine to simply use g_new0

As far as I understand AT+CHUP, it releases all active calls (active + 
incoming + dialing + alerting), so we do not need a call list and are 
not able to know that we already perform one.

Is it correct ?

Yes you're right.  I jumped ahead slightly.  Since I'd like to re-use
release_queue, it would be safer to check for the release list prior to
issuing any driver commands (just in case the release_list was set by
something else.)

[PATCH v2 0/8] emulator: add simple incoming call support

[=?unknown-8bit?q?Fr=C3=A9d=C3=A9ric?= Danis]

[-- Attachment #1: Type: text/plain, Size: 802 bytes --]

Add call related indicators, +CLIP, +CCWA, RING to signal incoming call,
ATA to allow reception and AT+CHUP to reject or finish
of an incoming call in HFP AG

Frédéric Danis (8):
  emulator: add defines for call, callsetup and callheld indicators
  emulator: add call, callsetup and callheld indicators
  emulator: add RING for HFP AG
  emulator: add incoming call API
  emulator: add +CLIP support for HFP AG
  voicecall: add ATA support for HFP emulator
  voicecall: add +CHUP support for HFP emulator
  emulator: add +CCWA support for HFP AG
